Managing manure nutrients is a high priority for livestock farmers for economic and environmental reasons. Iowa dairy and beef producers are invited to attend Iowa State University Extension and Outreach field days featuring a variety of manure management systems. The field days will be held in northwest and northeast Iowa during October.

“Manure is beginning to be recognized as a valuable asset rather than a waste product in the livestock operation,” said Beth Doran, Iowa State University Extension and Outreach beef program specialist. “How the manure is handled and stored can affect the financial return to the farming enterprise. The various ways dairy and beef producers handle manure will be the focus of the field days.”

Field day discussions will focus on nutrient management including various options and methods to manage total farm nutrient balance, manure management and nutrient runoff.

Northwest Iowa manure management field days:

Oct. 1

10 a.m. start, Multi-Rose Jerseys, Rock Rapids. Multi-Rose has a unique process to recycle solids from the free stall barn as bedding for the cows. At 11:30 a.m., the field day moves to the Jim Koedam farm, near Doon. Koedam uses a low-cost pumping system to apply feedlot liquids to nearby corn fields. The field day concludes with lunch and a tour of the Terry Van Maanen Dairy operation north of Rock Valley where participants may view a sand settling lane, three manure structures and how runoff from silage piles is prevented. 

Oct. 2

1 p.m. start, Chad and Dale Fertig Dairy, south of Wall Lake. This dairy operation has a drive-in sand settling pit and a newer heifer barn with manure storage.
